builddate=1970 - 1976The EMD DDM45 is a narrow gauge
diesel-electric locomotive built by EMD. It has eight axles in two trucks, giving it a D-Dwheel arrangement . The name means a D-D locomotive, M formeter gauge (the rails are a meter apart), 45 series. They were built for service in Brazil,South America . The Estrada de Ferro Vitória a Minas (EFVM) bought several in the early 1970s in order to expand their locomotive roster. The EFVM needed the most powerful single-engined locomotive available, and the SD45 represented the highest-rated model that EMD had to offer at the time.However, a big locomotive such as an SD45 with its three-axle trucks wasn't readily adaptable to the EFVM's narrow gauge trackage. The smaller
traction motor s of the meter gauge locomotive were unable to handle the full current capacity from the 3,600 HP prime mover. And so, EMD proposed the meter gauge version of the Flexicoil-D four-axle trucks, similar to those found under the domesticEMD DD35 ,EMD DD35A andEMD DDA40X locomotive model, creating the DDM45 in the process. The additional 2 traction motors of this design allowed full power to be used.Roster of DDM45s:
